Suspended arch tile structure



Nov. 23, 1954 F. D. HAZEN SUSPENDED ARCH TILE STRUCTURE Filed March 8, 1950 L INVENTOR. BY 7AM W ezaw' AW United States Patent one 2,694,992 Patented Nov. 23, 1954 2,694,992 SUSPENDED ARCH TILE STRUCTURE Frank I). Hazen, Pittsburgh, Pa., assignor to M. H.

Detrick Company, Chicago, Ill., a corporation of Delaware Application March 8, 1950, Serial No. 148,476 2 Claims. (Cl. 110-99) This invention relates to new and useful improvements in refractory tile, more particularly hanger brick tile used in suspended arch structures in furnaces and the like, and it is among the objects thereof to provide a tile shaped to adapt it for mounting between channels or other structural members and which shall be shaped for' insertion in the channels as a replacement part.

The invention will become more apparent from a consideration of the accompanying drawing, constituting a part hereof, in which like reference characters designate like parts and in which:

Fig. l is a view in perspective of a suspended arch structure with tile embodying the principles of this invention; 1Fig. 2 a front elevational view of a hanger brick or ti e;

Fig. 3 an end elevational view thereof taken along the line 3-3, Fig. 2;

Fig. 4 a vertical cross sectional view taken along the line 4-4, Fig. 2;

Fig. 5 a horizontal cross section taken along the line 5-5, Fig. 2; and

Fig. 6 a top plan view of a plurality of channel members partially broken away showing hanger brick partially in section and in plan.

With reference to the several figures of the drawing, numerals 1 and 2 designate a pair of channel members supported on beams 3 with refractory tile 4 and 5 suspended therefrom to constitute a furnace roof or arch. Hanger brick of the shape disclosed in my pending application Serial No. 44,842, filed August 18, 1948, now Patent No. 2,634,694, dated April 14, 1953, is shown in Figs. 2 to 5 and consists of a refractory brick 6 having flared grooves 7 with oppositely disposed ribs 8, the bottom of the groove 7 forming a square shoulder 9 which acts as a key for suspending arch tile 4, Fig. 1, which, as disclosed in the aforementioned application, are split members that are slotted to receive the entire lower portion of the hanger brick 6 as shown on the right-hand side of Fig. 1 of the drawing. The flared face 7 of the hanger brick rests upon the flanges of the channels 1 and 2, as shown in Fig. 1, being normally slid in position as the roof or arch is constructed. Adjacent tile 4 support the intermediate tile 5 which is keyed in the arch by the shoulders 10, Fig. 1.

In accordance with the present invention the grooves 7 of the tile, which are on opposite end faces of the tile, are curved at opposite corners as shown at 11 and 11a, Figs. 5 and 6. This grooving permits replacement of worn or broken tile without loosening the structural members 1 and 2 and without necessitating assembly of the tile by sliding them in from the edge of the channel members.

This function is shown in Fig. 6 of the drawing in which the hanger brick 6 is shown as placed between the channels and raised above the channel flanges at an angle, and then turned to the proper position between the channel supports. Such a construction of the hanger brick eliminates substantial costs in arch repairs and saves breaking up usable tile which need not be removed when repairs and replacements are made with the curved grooved tile as herein shown.

Although one embodiment of the invention has been herein illustrated and described, it will be obvious to those skilled in the art that various modifications may be made in the details of construction without departing from the principles herein set forth.

I claim:

1. A substantially rectangular hanger brick for suspended refractory roof tile having a grooved lower portion for supporting said refractory tile, said hanger brick having horizontal grooves extending transversely across the top portions of said grooved portions in the opposite ends thereof having divergent walls, the major portions of said grooves being of uniform depth and having gradually deepening portions at diagonally opposite ends thereof to provide a rounded corner between the bottom of each groove and a side face of said brick, said rounded corners being disposed diagonally opposite each other.

2. The combination with a pair of channel members, of a hanger brick for suspending refractory roof tile therefrom, said brick being substantially rcctangularly shaped and having recesses around its lower periphery to form grooves and upwardly facing shoulders parallel to and spaced from the lower end of said brick to constitute the lower end of the brick a key for supporting hanger tile, said hanger brick having a substantially V-shaped horizontal groove in opposite end faces thereof in said peripheral groove extending transversely of said end faces in upwardly spaced relation from said shoulders for seating on the flanges of supporting channel members, said V-shaped grooves being of uniform depth throughout the major portion thereof, one of said V-shaped grooves having a rounded corner at one end thereof and the other V-shaped groove having a rounded corner at the other end thereof to permit insertion of the brick between said pair of channel members for placement on the flanges of said channel members, said V-shaped grooves having square corners at the ends thereof opposite those having the rounded corners.
